subneting on HP-UX 10.20

[rx71]

Hello,

I'm trying to set network mask 255.255.255.128 on HP-UX 10.20 box with C-class address - 192.12.140.132. I know it means 0 subnets, but it works on another systems. Does anybody know any workaround for HP-UX 10.20 ?

Thank you in advance!

Best regards,
Roman

Why don't u try with netmask 255.255.255.192?

Are u sure other systems on whose this works fine are C-class systems?.

You can disable subnet checking with a nettune parameter.

nettune -s ip_check_subnet_addr 0

For 10.X, nettune changes do not do not survive reboots! Create a startup file in /sbin/rc2.d yypically /sbin/rc2.d/S341nettune that runs the nettune(s) that you need.

It works on Linux, Tru64 Unix, Solaris, also Cisco boxes. I will try nettune, but I can't find it - is it in any patch ?

Thank you again!

take a look under /usr/bin/contrib or you may have to apply the ARPA patch to get this functionality.
